Summary File 1 contains 100-percent United States decennial
Census data, which is the information compiled from the questions
asked of all people and about every housing unit. The Advance National
component of Summary File 1 describes the entire United States.
Population items include sex, age, race, Hispanic or Latino origin,
household relationship, and group quarters occupancy. Housing items
include occupancy status, vacancy status, and tenure (owner-occupied
or renter-occupied). There are a total of 171 population tables ("P")
and 56 housing tables ("H") provided down to the block level, and 59
population tables provided down to the census tract level ("PCT") for
a total of 286 tables. In addition, 14 population tables and 4 housing
tables at the block level and 4 population tables at the census tract
level are repeated by major race and Hispanic or Latino groups. The
data present population and housing characteristics for the total
population, population totals for an extensive list of race (American
Indian and Alaska Native tribes, Asian, Native Hawaiian, and Other
Pacific Islander) and Hispanic or Latino groups, and population and
housing characteristics for a limited list of race and Hispanic or
Latino groups. Population and housing items may be crosstabulated.
Selected aggregates and medians also are provided.
